The BBC website also says this below of Scotland:
*"From next week, the daily figures will also start to include all deaths where the virus is officially "suspected" to have been a factor, even if it has not been confirmed by testing.
Ms Sturgeon said this would increase the number of deaths on record, but would not speculate about how significant this could be.
She said she was "determined that information continues to be as accurate, comprehensive and up to date as possible" and that her government will be "as transparent as we can be"."*
So this may affect the trend for a week - the increase will presumably be higher than otherwise. Unless they announce the figures separately, so that like can be compared with like. (I know there is a non like for like element anyway, but this sounds as though it may mean that there is a significant one-off change.)
